WATER-GAG E.

SPECIFICATION forming part of Letters Patent No. 545,727, dated September 3, 1895.

Application filed October 5, 1894- To all whom t may concern:

Be it known thatwe, FRITZ RoCKsTRoH, MAX TEPPIG, and HERMANN HERZIG, subjects of the Emperor of Germany, residing at Goerlitz, Prussia, Germany, have invented certain new and useful Improvements in Water- Gages, of which the following is a specification.

Our improvements relate to water-gages, and more particularly to such having reflectors.

The object ofour invention is to provide reiiectors on watergages,which may be shortened or lengthened to fit different lengths of such gages. j

It is a well-known fact that the water-gages or glasses of boilers vary in length, and to provide a reiiector which may be easily and effectively adjusted and secured to a watergage the reflector is made of two sections, of which one is slidingly mounted on the other, and each of the sections is provided with a device for holding the said sectional reflector in position on the said gage. It' preferred, a safety or projecting jacket of two sections hinged to the respective reector-sections may also be provided. In such case the water gage or glass is entirely surrounded-for instance, in the rear by the reflector and in front by the jacket of transparent material or wire-netting. y

The invention will be more fully understood taken inv connection with the accompanying drawings, forming part hereof, and in which- Figure 1 is a front view of a water-gage provided with a movable reflector. Fig. 2 is a side view thereof. Fig. 3 is a rear view. Fig. 4L is a horizontal section, and Fig. 5 shows a side View, the several parts' being pushed together. Fig. 6 shows a modification of our water-gage, having a reflector and a safetyjacket. a horizontal section. Fig. 9 is a rear view, the jacket being opened, and Fig. 10 is a plan view thereof. Fig. 1l is a front View of a modification, the glass jacket being substituted by a jacket from wire-gauze. Fig.12 is a plan View thereof. Fig. 13 is a front cured to a metal frame.

Fig. 7 is side view thereof. Fig. S isv 'seri-2.1 No. 524,962. (No model.)

view, the'jacket being opened; and Fig. 14 is ored points are retractedl by the water Within the water-gage, so as to see the water-level from all sides, even at a greater distance, as shown by Fig. 1. j

A In order to be enabled to move the plates a b one upon the other, we provide'one plate a with screw-bolts a', which are guided within the slots b of the other plate b. The plates o. b are iixed or adjusted by means of the nuts d2. `At the lower and at the upper end the plates a b are fitted with spring-holders e', to which the watergage is secured by means of the nuts e.

In Fig. 1 the plates a b of the reflector are elongated or pushed outside. If it is desired to apply the reector toa smaller water-gage, it is only necessary to loosen the nuts a2 and to push together the plates, asshownin Fig. 4.

Amodication of the above-'described arrangement is represented in Figs. 6 to 10. Also in this construction is shown a reflector composed of two movable plates; but the reilector is provided with a movable safetyjacket, consisting of glass and preventing the water-gage from cracking, as the latter is secured against alteration of temperatureforinstance, in the backward movement of the locomotives. The said glass jacket consists of two superposed parts f g,which are se- These metal frames are hinged to the plates a by means of a pin h, and provisions are made for closing the jacket. In the example shown we effect this by a spring-pin i, behind which the end flaps of the metal frame are clamped.

In Figs. 11 to 14 is shown a modification in which the glass jacket is substituted by a jacket from wiregauze. While the glass jacket is designed to prevent the water-gages from cracking by reason of alteration of temperature, the jacket from wire-gauze has for its object to prevent the accidental breaking of the water-gages and the ying about of splinters.

It is obvious that by the described con-` struction the manufacture of the armature is greatly simplified, as for water-gages of different size the same armature may be used.

l. As anew article of manufacture a reflector adapted to be mounted on water-gages of different length, comprising two channeled or hollow sections, one fitting within the other and partly surrounding the said water-gage, a spring holder on the outer ends of each sec tion adapted to engage the end portion of the gage, one or more screws on one of the said sections, said screws passing through slots of the other section to allow of lengthwise adjustment and clamping of the sections, substantially as and for the purposes set forth.

2. In a water-gage, a reflector capable of being mounted on water-gages' of different length, comprising two channeled or hollowr sections, one fitting Within the other and partly surrounding the said water-gage, a spring holder on the outer ends of each section adapted to engage the end portion of the gage, one or more screws on one of the said sections passing through slots of the other sections to allow of lengthwise adjustment and clamping in place of the sections, in combination with a protecting jacket composed of two adjustable sections, which are hinged to the respective sections of the reflector, substantially as and for the purposes set forth.
